Anti-rotating insulating support and anti-rotating method thereof

Abstract

The invention relates to an anti-rotating insulating support and an anti-rotating method thereof. The anti-rotating method is characterized in that the outer side surface of a metal inner sleeve and the inner side surface of a middle medium are respectively provided with a first platform mutually fit along the direction of the pipe length so as to lead one part of a curve surface attached tightlybetween the metal inner sleeve and the middle medium to be attached tightly in a plane; an outer ring of the part of the cross section of the metal inner sleeve, provided with the first platform, is around flaw shape of a round flaw angle between 15 degrees to 90 degrees; the outer side surface of the middle medium and the inner side surface of the metal outer ring are respectively provided witha second platform fit along the direction of the pipe length so as to lead one part of a curve surface attached tightly between the middle medium and the metal outer ring to be attached tightly in a plane; and an outer ring of the part of the cross section of the middle medium, provided with the second platform, is a round flaw shape of a round flaw angle between 15 degrees to 60 degrees. The invention can prevent relative rotation among three-layer parts of the insulating support, simultaneously has simple method, easy processing, low cost and reliable work.

Description

technical field [0001] The invention relates to an insulating support part in a precision coaxial cable connector used in radio frequency and microwave transmission technology, in particular to an anti-rotation insulating support and an anti-rotation method thereof. Background technique [0002] Precision coaxial cable connectors used in radio frequency and microwave transmission technologies usually include components such as center conductors, insulating supports and outer conductors, and center conductors are usually divided into two parts, such as center conductor A and center conductor B, usually in The center conductor A is covered with an insulating support, and then inserted into the center conductor B and then screwed or welded into one body, and then the outer conductor is installed, and the electromagnetic wave is transmitted in the inner cavity of the outer conductor. The insulating support consists of three layers of metal inner sleeve, intermediate medium and m...

AI Technical Summary

Problems solved by technology

The insulating support consists of three layers of metal inner sleeve, intermediate medium and metal outer ring from the inside to the outside. The three-layer parts of the insulating support commonly used are all tubular components, and the inner ring and outer ring of the cross section of each tubular component are Complete circle, this structure makes the tightness between the three-layer parts poor, and the relative rotation between two parts often occurs. The misalignment caused by the mutual rotation between the three-layer parts will make the electromagnetic wave transmit in the inner cavity of the outer conductor. The performance index is affected, and at the same time, it will cause wear
